Subject [jira] Commented: (HADOOP-5869) TestQueueCapacities timeout in trunk.
Date Thu, 28 May 2009 00:21:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5869?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12713813#action_12713813
] 

Chris Douglas commented on HADOOP-5869:
---------------------------------------

Two issues are responsible for this. The first is HADOOP-5792, which caused TestQueueCapacities
to fail. Once reverted, HADOOP-4981 evidently introduces a second regression, which was ignored
because it was assumed that trunk remained the sole cause of the failure. Note that TestQueueCapacities
is also failing in the 0.20 branch.
